摘要
基于抚顺山龙峪、锦州沈家台及丹东变电井数字化水温观测资料,分析了国内外12例地震引起的水温同震效应,结果发现三口井水温数据均具有上升一下降一恢复的同震变化过程,基于12次地震震源机制解,分析出其中有3个走滑型地震,1个正断层型地震兼少量左旋走滑型地震,8个逆冲型地震。结果显示,三口井水温同震变化不受地震方位和震源机制的影响,水温同震下降幅度随震级的增大而增大,随震中距的增大而减小,三者之间有较好的对应关系。
Based on the digital water temperature observation data of Shanlongyu in Fushun,Shenjiatai in Jinzhou and Dandong substation well,we analyzed the co-seismic effects of water temperature caused by 12 earthquakes in domestic and foreign.It is noted that the co-seismic variation of water temperature in three wells always has the process of rising,falling and restoring.The focal mechanism solutions of the 12 earthquakes are calculated.And there are three strike-slip earthquakes and one with a little left-lateral strike-slip and 8 thrusting earthquakes.It is concluded that the variation of co-seismic is not affected by earthquake orientation and focal mechanism,and the decreasing range of water temperature increases with the increase of magnitude and decreases with the increase of epicenter distance.
